## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## RubyGems Metadata Scraper — Extract Package Data from RubyGems.org

The RubyGems Metadata Scraper extracts comprehensive package information from RubyGems.org, the official Ruby package registry. This Actor retrieves version details, download statistics, dependency trees, authorship, licensing, and source code links for any Ruby gem — ideal for dependency analysis, security auditing, market research, and compliance reporting.

### Use Cases

- **Dependency Analysis** — Map out full dependency trees for Ruby projects to identify transitive dependencies and version constraints.
- **Security Auditing** — Track gem versions and checksums (SHA) to verify package integrity and detect outdated or vulnerable dependencies.
- **Market Research** — Analyze download trends and author ecosystems to identify popular gems and emerging libraries.
- **License Compliance** — Extract license information from gems to ensure compliance with open-source policies.
- **Portfolio Tracking** — Monitor version updates and download growth for gems your organization depends on.

### Input

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `gemNames` | Array | Yes | List of Ruby gem names to scrape (e.g., rails, sinatra, devise) |
| `maxItems` | Number | No | Maximum gems to process (default: 100) |
| `proxyConfiguration` | Object | No | Proxy settings (optional) |

### Output

The Actor outputs a dataset with the following fields for each gem:

```json
{
  "name": "rails",
  "version": "8.1.3",
  "downloads": 735455152,
  "versionDownloads": 2112129,
  "authors": "David Heinemeier Hansson",

  "licenses": ["MIT"],
  "homepageUri": "https://rubyonrails.org/",

}
```

### Pricing

Pay per event: $0.0002 per gem scraped. No minimum fees. Proxy usage is optional — the RubyGems API is publicly accessible and does not require proxy rotation for typical usage.

### Limitations

- Only publicly available gems on RubyGems.org can be scraped.
- Gems that have been yanked or removed may return errors.
- Rate limiting may apply for very large batches — the Actor includes automatic retry logic.
- Dependency information includes only runtime and development dependencies as declared by the gem author.

### FAQ

**Q: Do I need a proxy?**
A: No. The RubyGems API is publicly accessible and typically does not block datacenter IPs. Proxy configuration is available as an optional setting.

**Q: Can I scrape private gems?**
A: No. This Actor only accesses publicly published gems on RubyGems.org.

**Q: What happens if a gem name does not exist?**
A: The Actor logs the error and continues processing the remaining gems. Failed lookups are recorded in the run statistics.

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## CLI example

```bash
echo '{
  "gemNames": [
    "rails",
    "sinatra",
    "devise"
  ],
  "maxItems": 100,
  "proxyConfiguration": {
    "useApifyProxy": true
  }
}' |
apify call klondikeking/rubygems-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,klondikeking/rubygems-scraper"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
